    Abstract - (Show below) - (Hide below)

    Covers new inductive voltage transformers used with electrical measuring instruments and protective devices at frequencies from 15 Hz to 100 Hz. Deals with transformers having separate windings, as well as auto-transformers, where suitable, but not transformers used in laboratories.
